DON'T CALL THEM DRUGS!!! THERE AREN'T DRUGS!!!! IS MEDICAL POTIONS OK
I will like to see a famous drug in this world. Something different than just for health. Like the movie Looper or Dredd. not copying the same way of projecting it. But having a drug that can make me do something more.
Like for example, I am have my mech parts inside my body and let's say in this game there is a famous drug called "Good toxic" and It can be consume in 3 ways inhale it, inject it drinking it. and in my mech body can create this effects.
A. If i do have problems with whatever mechanic parts needs to recharge then I inhale it. and gives me some temporally one hour or two till I get to a medic or a black market or whatever I need to do for my fixed up. And the after effect can be less percent of each mechanic parts i have in my body to defend my self about 10% each attack I do. And can last this effect by two to tree hours during game, and can be fixed fast the after effect If I go to a black market doctor or a non underground doctor.
B. If i need some healing then I have let's say this drug is called "Recharger" gives me some health points for more durability during some battle or when i run away the police and i did get shot and Inject it in my body, and the reaction of that drug could be that the health that restore me for that amount of time. Is ended and the health goes back to the normal state when i was injure or shot (this could be implemented in hard mode)
C. When i need some extra durability or run faster for my legs to scape or do whatever I want. I could drink let's say this drug is called "Pro" It can give you some durability in battle and make you run faster and jump higher (if this game have some sort of jump thing kind of mech specs) and can have all of the options above, but it will be hard to find and will cost the double or the triple of money. Because the "Pro Drug" can give you double of what you need. But the after effects can be temporal lost of accuracy,medium last health(meaning when gangs or police shot you you will lost the 5% of health) so you have to play very intelligent your move in battle or fighting. And this after effect can last 3 hours of gameplay or how the hours past inside game.
All this options can be used in Hard mode.. or all modes I will really like to see some real effects and after ones. this are my Ideas of the drugs and his after and during using it effects. And for the how many hours the after effect are last long. Because It will be real to see and play as long as they last It would be no challenge if i get the after effects and I don't get to see how I will react in game or what happen.
